The stamp position recognition unit 7 reads an image of the delivery object S by the first image acquisition unit 1-7 according to a sampling pulse signal described later, and recognizes the stamp sticking position from the read image. Generally, stamps use a special ink that emits light when irradiated with ultraviolet rays and then continues to emit light for a while (afterglow). Utilizing this, the stamp position recognition unit 7 irradiates the delivery object S with ultraviolet rays with a light immediately before acquiring the image, and acquires an image of the delivery object S in a state where the stamp is emitting light. The first image processing unit 15 recognizes the light emitting position in the acquired image, thereby

The stacker corresponding to the classification destination of the delivery object S is specified from the destination information and the stamp fee. For example, in the case of an address in Japan, the classification destination associated with the stacker is determined collectively by the addresses that match "○ chome" in the destination. The control unit 100 specifies, for example, the classification destination by referring to the correspondence information in which the destination information stored in the database and the classification destination are associated with each other. The correspondence information may be table data, information embedded in a function or program, or data stored in a database.
